Capture Every Conversation

Recording architecture asigură capturarea, stocarea securizată, și accesul la înregistrări pentru compliance, training AI, și quality assurance.

Recording Modes

Mono (Mixed)

Both parties mixed into single channel.

• Smallest file size
• Simple playback
• Limited for STT training

Basic

Stereo (Dual-Channel)

Caller on left, agent on right channel.

• Separate speaker analysis
• Better for STT training
• Standard pentru QA

Recommended

Dual-File

Separate files for each participant.

• Maximum flexibility
• Independent processing
• Higher storage cost
